its stability during the hiccup. A similar situation can arise
if the user selects a more traditional startup method, with
an auxiliary winding. In that case, the V
stops the output pulses whenever it is activated, that is to
Figure 50. At power on, output A is first activated and the frequency slowly decreases via the soft- -start capacitor
